Yes its just behind the front bearing housing, heres a pic of it and a close up so you can see the actual flats.

Hood,

And will you just make a new A type spindle nose and permanently attach it to the current spindle? Or will you make new the whole spindle with the nose?

Dan

I will just make a complete spindle, thats if I ever get time to get round to do it

Hood

Managed to get the Z hooked up and tested, have it set at 10m/min and its working well.
Also tried out the MPG via the MPG module and I am very impresed with the precise, smooth motion even at the x100 setting.
Heres a quick vid of the MPG being used.

Feels better than with the SS?

Dan

Yes Dan, by a long way. The SS/ESS does things the same way as the PP and in multistep mode it is sort of clunky, the CSMIO is very smooth just like you were commanding a feed. One other major difference is the PP/SS etc will buffer moves so for example if you have it set to multistep and 0.1mm increments you have to be careful you dont wind too fast or the axis will continue for a while after you stop, set the steps bigger and its even worse. The vid shows me at first in steps of 0.01mm then 0.1mm then finally 1mm, there is no buffering at all and the movement is very smooth between clicks.

Some nice progress here, Hood, looks great-

thanks for sharing-
Dave

Thanks Dave, just waiting for a motor for the X coming from your side of the world so wont be much more progress until it arrives
Hood

Thanks, Hood. That sounds really good! Got two Cincinnati machines (a mill and a lathe) awaiting retrofit and I am quite convinced now that the CS Lab controller is the way to go. Although the delayed pullout in threading would a be a problem on the lathe. Hope it gets sorted by the time I get to it.

Dan

Yes, looking good so far and hopefully it continues the same way. I like the SS and ESS but sadly Greg just didnt seem to want to go for more industrial type controllers, may be a mistake on his part, maybe not, time will tell but I think the Mach user base is moving away from the hobby only world and getting into production/industrial sized/style machines. There will always be the market for basic controllers that take place of the parallel port but the future, at least in my mind, is industrial quality and spec controllers.

Regarding the threading, not managed to do any testing with axis yet as I am waiting on a small motor arriving from the USA for the X. On screen its really hard to tell if it does pull out or if its delayed, some times it looks like it does, others not so only real axis tests will show it up. If it has the delay then they will need to get that sorted before anyone will take the controller seriously for a lathe and it would be a shame for that not to happen as so far it does look like its an extremely accomplished controller with industrial qualities.
